Katerina’s small, safe life in London is upended on Christmas Eve when her beloved mum passes away. Two days later, she sees her boyfriend of five years kissing the local librarian. Kat goes to bed and pulls the covers over her head, convinced she will never recover from these losses.
To Kat’s great surprise, her mum has left her four letters to guide her through her grief and an air ticket to Swedish Lapland for a wild adventure. Before Kat knows it, she’s at the top of the world with a backpack and her headstrong French bulldog, Olive.
